U.N. commissioner condemns latest Israel strike near school

United Nations Relief and Works Agency Commissioner-General Pierre Krahenbuhl criticized Israel on Sunday for not doing enough to protect civilians in Gaza after reports that a missile had struck a street just outside a U.N. school there for the second time in a week.

"This is, of course, another incident that generates both shock and disbelief at the fact that it could happen again," Krahenbuhl said on CBS' "Face the Nation."

Krahenbuhl confirmed there were multiple deaths from the latest strike. Asked if U.N. facilities were protecting members of Hamas, he said there were 250,000 people sheltered in U.N. schools because of the conflict in Gaza and that in at least three instances inspections turned up weapons caches on premises that were condemned and disclosed to international authorities.

"But, clearly, nobody can suggest that because weapons were found in one premise this can be in any sense a justification for shelling other schools and endangering the lives of displaced people in the middle of a war zone," Krahenbuhl said.
